Literal improvements in C# 7.0

There were two types of literals supported in C# prior to C# 7.0. They are decimal literals and hexadecimal literals. For example, 490 is a decimal literal, whereas 0x50A or 0X50A is a hexadecimal literal, equivalent to the decimal value 490. Please note that the prefixes 0x and 0X define the same thing.

Here's an example for you to easily understand how a hexadecimal literal is used in C#:

 
    class Program 
    { 
      static void Main(string[] args) 
      { 
        double height = 490; 
        double width = 1290; 
 
        double heightInHex = 0x1EA; // equivalent to decimal 490 
        double widthInHex = 0x50A; // equivalent to decimal 1290 
 
        Console.WriteLine("Height: " + heightInHex + " Width: " + widthInHex); 
      } 
    } 

Along with C# 7.0, Microsoft added more support to literals, and they...
